A subset of stretchand buster/unstable packages with
systemd-related regressions reverted. As some folks want, this removes
all uses of libsystemd0 which is not the proper way to
go for a generic distribution as libsystemd0 is harmless without systemd
itself. Its removal, though, is a quick way to ensure using non-systemd
code paths as too many packages confuse what's supposed to be run-time
detection with compile-time detection of systemd, and thus break things
like shutdown or suspend on non-systemd systems. Deprecated!
Please migrate to Devuan or a similar derivative. The buster/unstable
repository has already been removed (after not getting any updates for
4 months).
